Abstract:
A microwave experiment was installed at Scott Base to measure microwave emission of atmospheric chlorine monoxide (ClO) near 1.1 mm wavelength by a heterodyne spectrometer. The heterodyne techniques allows very high spectral resolution revealing the details of the pressure-broadened line shape. Because the line is pressure broadened, its shape is sensitive to the vertical distribution of the ClO ... and that distrubution can be retrieved with vertical resolution of about 10km. The data (raw = times and recorded microwave emission spectra, derived = column amounts and vertical profile information of chlorine monoxide (ClO)) are held at SUNY and in the NDACC database.

Description:
The data is submitted to the international Network for the Detection of Atmospheric Composition Change (NDACC). This public record is available through an anonymous ftp or by a clickable map linking sites with data directories.

Quality
The data (raw = times and recorded microwave emission spectra, derived = column amounts and vertical profile information of chlorine monoxide (ClO)) are held at the State University of New York (SUNY), in the NDACC database and at NIWA.
